While it may not be as readily accessible as porn, the research on porn is nonetheless abundant.

Just last week, while the ABC ran a panel discussion on Australian attitudes toward porn, another new study implicating porn made headlines: "Anal sex study shows climate of painful coercion affecting young girls."

The study found "the main reason that young people also cited for engaging in the act is that boys 'wanted to copy what they saw in pornography'."

There are hundreds more studies like this one. So many, in fact, that studies are being combined in meta-analyses to assess the overall trends across thousands of pieces of data: sexual assault study shows link to pornography use; pornography use linked to higher rape acceptance attitudes; nearly half of all young women have been sexually coerced; and so on.
